HOSE-COUPLING.

SPECIFICATION formingpart of Letters Patent No. 625,831, dated May 30,1899. Application filed September 2d, 1898. Serial No. 691,786. (Nomodel.)

To a/ZZ whom t may concern:

Be it kn own that I, ANDREW JACKSON GoN- LEY, a citizen of the UnitedStates, residing at Luling, in the county of Caldwell and State ofTexas, have invented a new and useful Hose-Coupling, of which thefollowing is a specification.

This invention is a new and useful pipecoupling for air-,pipes used uponrailway-cars for air-brakes, the object of the invention being toprovide an exceedingly cheap, simple, and efficient construction ofcouplingthe sections of which can be connected more easily than thecouplings now in use and one in which the air-pressure will tend to bindthe` sections closer together.

Another object of the invention is to provide aconstruction in which thecoupling and supporting parts shall be 4so arranged and constructed thatthe movement of the car will not interfere with the successful operationof the coupling.

With these objects in view my invention consists in the peculiarconstruction of the several parts and in their novel combination andarrangement, all of which will be fully described hereinafter, andparticularly pointed out in the appended claims.

In the drawings forming part of this speciicat-ion, Figure lis a Viewshowing my invention as applied to the end of a car. Fig. 2 is averticallongitudinal section of the coupling and connecting parts. Fig. 3 is asectional view on the line 3 3 of Fig. 2; Fig. t is a detail view of thetubular conn ecting-pin.

My invention is applicable to all kinds of cars and couplers, andconsequently I have shown it applied to a freight-car equipped with anordinary' pin-and-link coupling.

An angular bracketA is attachedto the bottom of the draw-head and car,thevertical member of said bracket depending, as shown, and havingalarge circular opening A made therein, through which passes the rear endB of the body B of thecoupling, said body being supported4 by lmeans ofa hinged loop (J, hinged at its upper end to the bracket A and passingbeneath the body of the coupling, said body being recessed at this pointin lorder to hold 5o `the same in aflxed position, a limited amount -inthe opposing member.

of play being given, inasmuch as the loop C isnot quite so wide as therecess'. A supporting-block D is arranged upon the hinged loop, saidblock being substantiallyin the form of a ring and one portion thereofthicker than `the other, so that the body of the coupling can beadjusted up or down by simply turning the thick or thin portionof thesupporting-block between the loop and the body of the coupling.'

The coupling is formed with a collar B2, and between this collar andthevertical member of the bracketAis arranged a coil-spring E, saidspring being largerin diameter at the rear end than at the forward endin order to permit a slight movement of the rear end B. The bell-shapedmouthpieces F of the coupling are screwed into the body of saidcoupling, one of the said bell-shapedlnouthpieces serving to secure thetubular coupling-pin G within the bod y of the coupling, said pin havinga collar G, against which the end of the bell iits, the short end G2 ofsaid coupling-pin passing through a lock-nut H and also through a rubbergasket I, which is held in place upon the shoulder K of the body bymeans of the lock-nut I-I, and the longer arm G3 of the coupling-pin isadapted to pass througha similar gasket arranged in a similar manner inthe opposing member of the coupling. In order to effect a coupling, itis only necessary to force the longer member of the coupling-pin intothe opposing coupling member, and in case' the respective members shouldit loosely on account of wear or other causes the air-pressure wouldtend to bind the rnbber gasket I against the lock-nut H and by impingingupon the coupling-pin hold the separate parts in operative connection,it being of course understood that the bell-shaped mouthpieces arebrought into contact` with each other, as clearlyillustrated in Fig. 2.

Whenever it is desired to change the coupling-pinfrom .one member to'another, it is only necessary to remove the bell-shaped mouthpiece,withdraw the pin, and insert it The supportingloop being hinged willpermit a limited longitudinal movement of the coupling in a rearwarddirection; but inasmuch as said supf Letters Patent of the UnitedStates, is-

1. In a hose-pipe coupling of the kind described, the combination withthe angular bracket, of the U-shaped Supporting-loop pivotally attachedto said bracket, the body portion of the coupling supported by said loopand passing through the apertu red end of the bracket, the springarranged between said bracket and body portion, and the ad-A justablesupporting-block arranged between the supporting-loop and the bodyportion,

substantially as shown and described.

2. In a hose-pipe coupling of the kind described, the combination withthe angular bracket, of the U-shaped supporting-loop pivotally attachedto said bracket, the body portion of the coupling supported by said loopand passing through the apertured end of the bracket, the springarranged between said bracket and body portion, the adjustablesupporting-block arranged between the supporting-loop and the bodyportion, the detachable tubular coupling-pin having a shoulder, and thebell-shaped mouthpiece adapted to bear against the shoulder,substantially as shown and described.

3. In a hose-pipe coupling of the kind described, the combination withthe angular bracket, of the U-shaped supporting-loop pivotally attachedto said bracket, the body portion of the coupling supported by said loopand passing through the apertured end of the bracket, the springarranged between said bracket and body portion, the adjustablesupporting-block arranged between the supporting-loop and the bodyportion, the detachable tubular coupling-pin having a shoulder, thebell-shaped mouthpiece adapted to bear against the shoulder, and therubber gasket and lock-nut, all arranged and adapted to operatesubstantially as shown and described.
